Tom Hooper may have his Oscar for directing The King's Speech to encourage him, but the British director was still taking on a mammoth task with the big screen adaptation of global stage hit Les Miserables.
If directing the Paris-set blockbuster wasn't enough, he thought he'd make it just a little bit more interesting, with his star cast - Hugh Jackman, Russell Crowe, Anne Hathaway, Eddie Redmayne and Amanda Seyfried, to name a few - all singing live for every take, the first time a musical film has been made in this way.
WATCH the cast in action above in our behind-the-scenes clip.
Les Miserables will be in UK cinemas on 11 January next year. Watch the first trailer below - was Hooper right to make his cast sing?
